Description
Verfahren zur Herstellung eines neuen Schwefelfarbstoffes. Es wurde gefunden, d'ass man .einen neuen Schwefelfarbstoff erhält, wenn man das Leukoderivat des Indophenols, das erhalten wird durch Kondensieren eines Gemisches, bestehend aus gleichen Teilen Carba.zol und N-Äthyloarba.zol, mit Nitrosophenol, in Ge genwart von Harnstoff schwefelt. Der neue Farbstoff stellt ein dunkles Pulver dar, welches sich in konzentrierter Schwefelsäure mit graublauer Farbe löst. Er liefert eine gelbe Hydrosulfitküpe und färbt Baum wolle in grünlichblauen Tönen an.
Die Färbungen sind sehr gut licht-. und wasch echt und besitzten gute Chlorechtheit. Beispiel <B>28</B> Teile des Indophenols, welches man durch Kondensieren einer Mischung von glei chen Teilen N-Äthylcarbazol und Carbazol mit Nitrosophenol erhält; -werden in Form einer zirka. 20 %igen Paste in eine konzen trierte Poly sulfidlösung, bestehend aus 29 Teilen kristalliiertem Na.triümsulfid, 12 Tei len Schwefel und 15 bis 20 Teilen Wasser, eingetragen.
Diese Mischung wird so lange gerührt, bis das Indophenol vollständig re duziert ist. Hierauf gibt man der Masse 12 Teile Schwefel und 20 Teile Harnstoff zu und trocknet im Vakuum. Das zerkleinerte Produkt wird in einem geeigneten Ofen auf 200 bis 220 erwärmt, bis die Schwefelwasser stoffentwicklung aufgehört hat. Nach dem Erkalten wird die Masse fein pulverisiert, mit einer verdünnten Natriumsulfidlösung extrahiert, mit Wasser und verdünnter Salz säure gewascben und getrocknet.
Process for the production of a new sulfur dye. It has been found that a new sulfur dye is obtained if the leuco derivative of indophenol, which is obtained by condensing a mixture consisting of equal parts of Carba.zol and N-Äthyloarba.zol, with nitrosophenol, in the presence of Urea is sulphurous. The new dye is a dark powder that dissolves in concentrated sulfuric acid with a gray-blue color. He delivers a yellow hydrosulfite vat and dyes cotton in greenish-blue tones.
The colorations are very light. and wash real and have good chlorine fastness. Example 28 parts of the indophenol, which is obtained by condensing a mixture of equal parts of N-ethylcarbazole and carbazole with nitrosophenol; -be in the form of an approx. 20% paste in a concentrated poly sulfide solution, consisting of 29 parts of crystallized Na.triümsulfid, 12 parts of sulfur and 15 to 20 parts of water, registered.
This mixture is stirred until the indophenol is completely reduced. Then 12 parts of sulfur and 20 parts of urea are added to the mass and it is dried in vacuo. The crushed product is heated to 200 to 220 in a suitable oven until the evolution of hydrogen sulphide has ceased. After cooling, the mass is finely pulverized, extracted with a dilute sodium sulfide solution, washed with water and dilute hydrochloric acid and dried.
